How does Ergothioneine's stability compare to other thiols and antioxidants in organisms?

Label:chem

Topic
Ergothioneine (ERG) has a standard redox potential (E 0 =−0.06 V). Other thiols and antioxidants include glutathione (E 0 =−0.24 V), lipoic acid, vitamin C, and vitamin E (E 0 =−0.2 to −0.32 V).
Answer
Ergothioneine (ERG) exhibits lower reactivity, greater resistance to autooxidation, and higher chemical and thermal stability compared to most thiols and antioxidants in organisms like glutathione, lipoic acid, vitamin C, and vitamin E.
